If a polynomial function f(x) has roots 0,4,and 3+ √11,what must also be a root of f(x) 3+i√11

3 -

Step-by-step explanation:

Radical roots occur in conjugate pairs.

3 + is a root then so is 3 -

Step-by-step explanation:

The function has a grade of 4, becaus it has 4 roots.

Now, if one of its roots is , it means there fourth is , because square roots have two results, one positive and one negative.

So, the function cannot have a positive square root solution and not have a negative root solution.

Therefore, the right answer is .

step-by-step explanation:

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
